BUOYANCY AND STABU.ITY OF TROOP TRANSPORTS. 



DISCUSSION. 



The President : — Professor Hovgaard's very admirable paper is now open for discus- 

 sion, gentlemen. It is especially rich, in the opinion of the Chair, in topics for discussion. 



Mr. Fred B. Webster, Member: — In commenting on Professor Hovgaard's excellent 

 paper, I wish to state that the importance of this subject, as well as the method outlined, 

 can hardly be over-emphasized. While I do not contend that other efficient methods for 

 safeguarding the buoyancy and stability of damaged vessels cannot be devised, I believe 

 that the subdivision of a ship into watertight compartments by transverse bulkheads is the 

 best method so far proposed.
